NOTE! Before you run the installation, you must extract the entire ZIP file to a temporary directory. Just double-clicking on the MSI files inside the ZIP will NOT work. Before you begin, please read the installation instructions at http://pginstaller.projects.postgresql.org Also see the FAQ available at http://www.postgresql.org/docs/faqs.FAQ_windows.html The files postgresql-8.1.msi and postgresql-8.1-int.msi contain PostgreSQL version 8.1.4. The reason for naming the files 8.1 is because the method used to upgrade the installation does not permit the filename to be changed. If you install directly from the 8.1.4 MSI file, your system will contain version 8.1.4 from the start and there is no need to upgrade it to 8.1.4. To upgrade from an earlier 8.1 release, please use the enclosed "upgrade.bat" file. Or look at it and adapt any commands as necessary. If you need to add or remove a feature afer you have upgraded, you must use the this version of the MSI file.
